The HMI controller records the friction torque and calculates the friction coefficient by following Equation 1 [121.
(1), (9) Both tools have rotational axes to prevent dancers from using friction when performing turnout, but neither provides the exact static friction torque of the device.
4, b, it is intended to test the hypothesis of constant friction torque accepted in the case of dry friction pairs for the symmetrical rotor; if the assumption is confirmed, it allows for finding the coefficient of sliding friction from the rotation pair, parameter required for the simulation of the asymmetric rotor motion.
Specifications include maximum RPM of 6000, static friction torque range from 0.044 ft.
